A manufacturing process of a negative-carbon dioxide emitting artificial, stonelike material comprising:
- (a) mixing a brine slurry comprising water, Mg(OH)2, and one or more nitrate, sulfate, sodium, chloride, and potassium, with slag to form a concrete mixture;
- (b) pouring the concrete mixture into a structural component mold to form a poured concrete mixture;
- and then,
- (c) curing the poured concrete mixture from step (b) in the structural mold to form a negative-carbon dioxide emitting artificial, stonelike material.

The manufacturing process of claim 11, wherein the amount of sulfate present in the brine slurry ranges from about 1 wt. % to about 10 wt. %.
-85. (canceled)
A method for reducing carbon emissions comprising:
- (a) mixing a brine slurry comprising water and Mg(OH)2, with slag and optionally at least one aggregate to form a cementitious mixture;
- (b) pouring the cementitious mixture into a structural component mold to form a poured cementitious mixture;
- (c) curing the poured cementitious mixture from step (b) in the structural mold to form a negative-carbon dioxide emitting cementitious material;
- thereby forming a negative-carbon dioxide emitting cementitious material that absorbs and prevents the emission of carbon dioxide.
